Technical Field

[0001] This invention belongs to the field of photovoltaic cast-in-place pile reinforcement cage technology, specifically a device and method for manufacturing continuous stirrups for photovoltaic cast-in-place pile reinforcement. Background Technology

[0002] In existing technologies, the construction of support foundations in new energy projects requires a large number of cast-in-place reinforced concrete column cages, typically reaching tens of thousands. As a crucial component of the support foundation, the fabrication quality of these reinforced concrete column cages directly impacts the overall quality of photovoltaic project support foundation construction.

[0003] Under existing methods for fabricating reinforced concrete column cages, the on-site welding of main bars and stirrups is typically done manually. This process is susceptible to variations in worker skills, experience, and workplace conditions, leading to problems such as misalignment, excessively large or small spacing of the reinforcing bars, and consequently affecting foundation quality. This not only requires highly experienced workers but also results in low production efficiency, making it difficult to meet the demands of large-scale photovoltaic projects.

The support plate is provided with multiple sets of evenly installed in the grooves opened on the side wall of the support roller. The multiple sets of support plates support the stirrups and separate the main bars. A recycling assembly is disposed in the middle of the support roller. The recycling assembly recycles the support plate into the chute. The recycling assembly includes an electromagnetic rod fixedly installed at the center of the rotating shaft. A connecting plate is fixedly installed in the middle of the side of the support plate near the rotating shaft. The connecting plate can be attracted by the energized electromagnetic rod. Support blocks are fixedly connected to both ends of the side of the chute near the rotating shaft. A spring is fixedly installed on the top of the support block. The end of the spring away from the support block is fixedly connected to the side wall of the support plate.

[0007] Preferably, it also includes a limiting component, which includes a mounting groove formed on the side of the support plate away from the rotating shaft, and limiting blocks are installed at equal intervals in the mounting groove. The bottom sides of the limiting blocks are rotatably mounted on the inner wall of the mounting groove via mounting shafts, and torsion springs are fixedly installed at the connection positions between the limiting blocks and the inner wall of the mounting groove.

[0008] Preferably, the inner wall of the mounting groove has a limiting hole, the limiting holes are arranged in pairs, each pair of limiting holes is arranged on both sides of the limiting block, the end of the limiting block has a groove in the middle, the two side walls of the groove have through holes, the insertion rod is slidably installed in the middle of the through hole, the insertion rod is adapted to the limiting hole, the end of the insertion rod located inside the groove is fixedly connected to a lever, the insertion rod is sleeved with a second spring, the two ends of the second spring are fixedly connected to the inner wall of the groove and the lever respectively.

[0009] Preferably, a fixing block is fixedly installed in the middle of the groove, the fixing block is located in the middle of the two levers, and a magnetic block is fixedly installed on the side wall opposite to the lever and the fixing block, the magnetic block can be attracted to the fixing block.

[0010] Preferably, a guide rod is fixedly installed inside the groove, and the end of the lever is slidably sleeved on the guide rod.

[0011] Preferably, the end of the lever away from the guide rod extends to the outside of the groove.

[0012] Preferably, the rotating shaft is installed in the mounting cavity opened in the middle of the support roller, and flange plates are fixedly installed at both ends of the support roller, with the flange plate on the side closer to the motor being fixedly connected to the rotating shaft.

[0013] Preferably, the support roller consists of a roller core and a shell, the shell covering the outside of the roller core, the roller core being made of aluminum and the shell being made of steel.

[0014] A method for fabricating continuous stirrups for photovoltaic cast-in-place piles, applicable to the aforementioned continuous stirrup fabrication device for photovoltaic cast-in-place piles, includes the following operational steps: S1. Select multiple target limiting blocks with appropriate spacing, and push the lever on the end of the limiting block towards the middle. The lever drives the insertion rod to move and disengage from the limiting hole, thus removing the limiting of the limiting block. Under the action of the torsion spring, the limiting block becomes perpendicular to the support plate. S2. Multiple circular stirrups are sequentially sleeved on the outside of the support plate from the end of the support roller, and the support plate is supported by a pair of springs, so that the side wall of the support plate is supported on the inside of the stirrups. S3. Multiple stirrups pass through the limiting block on the support plate in sequence. During the movement of the stirrups, the limiting block is rotated. When the stirrups have completely passed the limiting block, the limiting block is restored to a position perpendicular to the support plate by the torsion spring. Multiple stirrups are respectively attached to the side of a limiting block. The limiting block limits the multiple stirrups so that the spacing between each stirrup is equal. S4. Insert multiple long-axis main ribs sequentially from the end of the support roller along its length into the middle of two adjacent support plates. The multiple main ribs are evenly distributed on the outside of the support roller, and the outer wall of the main ribs contacts the inner side of the stirrups. Drive the support roller to rotate intermittently through the motor and reducer, and weld the main ribs and stirrups together in sequence. S5. After welding is completed, the electromagnetic rod is energized, and the electromagnetic rod generates a magnetic force that attracts the connecting plate and the support plate to move into the groove, so that the side of the support plate no longer abuts the inside of the stirrup. Then the steel cage, which is welded from multiple stirrups and main bars, is removed from the support roller, completing one production cycle. After that, the electromagnetic rod is de-energized, and the support plate is reset by a spring, so that the next manufacturing process can continue.

[0015] The beneficial effects of this invention are as follows: 1. The present invention provides a device and method for fabricating continuous stirrups for photovoltaic cast-in-place piles. By incorporating a motor, support rollers, support plates, and a recycling assembly, the device facilitates the positioning of stirrups and main reinforcement bars. In use, multiple annular stirrups are sequentially fitted onto the outside of the support plate from the end of the support roller. A pair of support plates are supported by springs, ensuring that the sidewalls of the support plates support the inner sides of the stirrups, thus stably installing the stirrups on the outside of the support roller. Then, multiple long-axis main reinforcement bars are sequentially inserted from the end of the support roller along their length into the space between two adjacent support plates. The main reinforcement bars are evenly distributed on the outside of the support roller, with their outer walls contacting the inner sides of the stirrups. The motor and reducer drive the support rollers to rotate intermittently, facilitating the rapid welding of multiple main reinforcement bars and stirrups together sequentially. During the welding process, there is no need for manual adjustment of the relative positions of the main reinforcement bars and stirrups, allowing multiple stirrups and main reinforcement bars to be welded together evenly. This simplifies the operation, improves welding efficiency, and effectively solves problems such as misalignment, excessive or insufficient spacing of the reinforcement bars, ensuring the foundation quality of the reinforcement cage. After welding, the electromagnetic rod is energized, generating an attractive force that draws the connecting plate and support plate into the chute. This prevents the side of the support plate from contacting the inside of the stirrups, reducing friction with the product and making it easier to remove the reinforcement cage from the support rollers.

[0016] 2. The photovoltaic cast-in-place pile reinforcement continuous stirrup manufacturing device and method of the present invention, by setting a limiting component to facilitate the limiting of stirrups, allows for the determination of the spacing between two adjacent limiting blocks as needed, so as to adjust the spacing between stirrups and meet more usage requirements. When installing stirrups, one stirrup is first put into the end of the support roller, and then the stirrup passes through multiple limiting blocks in sequence. During the movement of the stirrup, the limiting blocks are rotated. When the stirrup has completely passed the limiting blocks, the torsion spring makes the limiting blocks return to a position perpendicular to the support plate, so that the stirrup is in contact with the limiting block closest to the motor. Similarly, when installing the second stirrup, the second stirrup is in contact with the limiting block second closest to the motor, and so on, so that multiple stirrups are put into the support roller in sequence. In this way, the limiting blocks limit the multiple stirrups respectively, so that the spacing between each stirrup is equal, so that the welded product has a better stress effect.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1: As Figures 1 to 6 As shown in the figure, a photovoltaic cast-in-place pile reinforcement continuous stirrup fabrication device according to an embodiment of the present invention includes a frame 1, a motor 2, a reducer 3, a support roller 4 and a rotating shaft 7. The motor 2 is fixedly installed on the top of the frame 1, the reducer 3 is fixedly installed on the output end of the motor 2, and the rotating shaft 7 is fixedly installed in the middle of the support roller 4. One end of the rotating shaft 7 extends through to the outside of the support roller 4 and is fixedly connected to the output shaft of the reducer 3. Support plate 5, the support plate 5 is provided with multiple sets and evenly installed in the sliding grooves 6 opened on the side wall of the support roller 4, the multiple sets of support plates 5 support the stirrups and separate the main bars; A recycling assembly is disposed in the middle of the support roller 4. The recycling assembly recycles the support plate 5 into the chute 6. The recycling assembly includes an electromagnetic rod 8 fixedly installed at the center of the rotating shaft 7. A connecting plate 11 is fixedly installed in the middle of the side of the support plate 5 near the rotating shaft 7. The connecting plate 11 can be attracted by the energized electromagnetic rod 8. Support blocks 9 are fixedly connected to both ends of the side of the chute 6 near the rotating shaft 7. A spring 10 is fixedly installed on the top of the support block 9. The end of the spring 10 away from the support block 9 is fixedly connected to the side wall of the support plate 5. During operation, multiple annular stirrups are sequentially fitted onto the outside of the support plate 5 from the end of the support roller 4. The support plate 5 is supported by spring 10, ensuring the sidewalls of the support plate 5 are supported by the stirrups. This securely installs the stirrups on the outside of the support roller 4. Then, multiple long-axis main ribs are sequentially inserted from the end of the support roller 4 along their length into the spaces between adjacent support plates 5. The main ribs are evenly distributed on the outside of the support roller 4, with their outer walls contacting the inner sides of the stirrups. The motor 2 and reducer 3 drive the support roller 4 to rotate intermittently, facilitating the sequential welding of the main ribs and stirrups together. During the welding process, it is not necessary to manually adjust the relative positions between the main bars and stirrups at all times. Multiple stirrups and main bars can be welded together evenly, making the operation simpler and improving the welding efficiency. It effectively solves problems such as misalignment of the reinforcing bars, excessive or insufficient spacing, and ensures the foundation quality of the reinforcing cage. After welding, the electromagnetic rod 8 is energized, and the electromagnetic rod 8 generates a magnetic force, which attracts the connecting plate 11 and the support plate 5 to move into the sliding groove 6. This makes the side of the support plate 5 no longer abut against the inside of the stirrups, reducing friction with the product and making it easier to remove the reinforcing cage, which is made up of multiple stirrups and main bars, from the support roller 4.

[0022] It also includes a limiting component, which includes a mounting groove 12 formed on the side of the support plate 5 away from the rotating shaft 7. Limiting blocks 13 are installed at equal intervals in the mounting groove 12. The bottom sides of the limiting blocks 13 are rotatably mounted on the inner wall of the mounting groove 12 via mounting shafts, and torsion springs are fixedly installed at the connection points between the limiting blocks 13 and the inner wall of the mounting groove 12. During operation, multiple limiting blocks 13 are installed on the support plate 5 to limit the movement of the stirrups. When installing the stirrups, one stirrup is first inserted from the end of the support roller 4, and then the stirrup passes through multiple limiting blocks 13 in sequence. During the movement of the stirrup, the limiting block 13 is rotated. When the stirrup has completely passed the limiting block 13, the torsion spring causes the limiting block 13 to return to a position perpendicular to the support plate 5, so that the stirrup is in contact with the limiting block 13 closest to the motor 2. Similarly, when installing the second stirrup, the second stirrup is in contact with the limiting block 13 second closest to the motor 2. This process is repeated to install multiple stirrups onto the support roller 4. In this way, the limiting blocks 13 limit the multiple stirrups respectively, so that the spacing between each stirrup is equal, so that the welded product has a better stress effect and ensures the foundation quality of the steel cage.

[0023] Limiting holes 21 are provided on the inner wall of the mounting groove 12. The limiting holes 21 are arranged in pairs, with each pair of limiting holes 21 corresponding to both sides of the limiting block 13. A groove 14 is provided in the middle of the end of the limiting block 13. Through holes 15 are provided on the two side walls of the groove 14. A rod 16 is slidably installed in the middle of the through hole 15. The rod 16 is adapted to the limiting hole 21. A lever 20 is fixedly connected to the end of the rod 16 located inside the groove 14. A spring 17 is sleeved on the rod 16. The two ends of the spring 17 are fixedly connected to the inner wall of the groove 14 and the lever 20, respectively. During operation, multiple limiting blocks 13 are provided. The distance between two adjacent limiting blocks 13 can be determined as needed to adjust the spacing between the stirrups. The distance is adjusted to meet more usage needs. For the limiting block 13 that is not needed temporarily, by rotating the limiting block 13, the limiting block 13 is tilted and stored in the mounting groove 12. The spring 17 pushes the insertion rod 16 outward along the through hole 15, so that the end of the insertion rod 16 is inserted into the limiting hole 21 on the inner wall of the mounting groove 12, thereby limiting the limiting block 13 tilted in the mounting groove 12 without interfering with the movement of the stirrup along the outer wall of the support plate 5. For the limiting block 13 that needs to be used, by moving the lever 20 on the end of the limiting block 13 to the middle, the lever 20 drives the insertion rod 16 to move and disengage from the limiting hole 21, removing the limitation of the limiting block 13. Under the action of the torsion spring, the limiting block 13 is made perpendicular to the support plate 5, so that the stirrup can be limited by the limiting block 13.

[0024] A fixing block 19 is fixedly installed in the middle of the groove 14. The fixing block 19 is located in the middle of the two levers 20. A magnetic block 24 is fixedly installed on the side wall opposite to the fixing block 19 of the lever 20. The magnetic block 24 can be attracted to the fixing block 19. When working, when the levers 20 on both sides are moved to the middle, when the end of the insertion rod 16 is completely retracted into the through hole 15, the lever 20 is in contact with the side wall of the fixing block 19. The magnetic block 24 attracts the lever 20 to the side wall of the fixing block 19, thereby limiting the lever 20 and preventing it from resetting. This ensures that the insertion rod 16 always remains inside the through hole 15, so that the limiting block 13 will not be obstructed during left and right swinging.

[0025] A guide rod 18 is fixedly installed inside the groove 14, and the end of the lever 20 is slidably sleeved on the guide rod 18. During operation, the guide rod 18 restricts the movement direction of the lever 20, making the movement of the lever 20 more stable.

[0026] The end of the lever 20 away from the guide rod 18 extends to the outside of the groove 14; during operation, this increases the force-bearing position of the lever 20, so that the lever 20 can be moved.

[0027] The rotating shaft 7 is installed in the mounting cavity opened in the middle of the support roller 4. Flange plates 25 are fixedly installed at both ends of the support roller 4, and the flange plate 25 near the motor 2 is fixedly connected to the rotating shaft 7. During operation, the rotating shaft 7 and the support roller 4 are fixedly connected together through the flange plate 25, and the flange plate 25 can be disassembled to maintain the internal structure of the support roller 4.

[0028] Example 2: Figure 7 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the support roller 4 is composed of a roller core 22 and a shell 23, the shell 23 covering the outside of the roller core 22, the roller core 22 being made of aluminum material, and the shell 23 being made of steel material; during operation, using aluminum material to manufacture the main roller core 22 of the support roller 4 can reduce the overall weight of the support roller 4, thereby reducing the burden on the rotating shaft 7 and extending the service life of the rotating shaft 7; using steel material to manufacture the outer shell 23 can enhance the external strength of the support roller 4, making it wear-resistant and corrosion-resistant, which is beneficial to extending the service life of the support roller 4.

[0029] like Figure 8 As shown, a method for fabricating continuous stirrups for photovoltaic cast-in-place piles is described. This method is applicable to the aforementioned continuous stirrup fabrication device for photovoltaic cast-in-place piles and includes the following operational steps: S1. Select multiple target limiting blocks 13 with appropriate spacing, and push the lever 20 on the end of the limiting block 13 towards the middle. The lever 20 drives the insertion rod 16 to move and disengage from the limiting hole 21, thus removing the limiting of the limiting block 13. Under the action of the torsion spring, the limiting block 13 becomes perpendicular to the support plate 5. S2. Multiple circular stirrups are sequentially sleeved from the end of the support roller 4 onto the outside of the support plate 5, and the support plate 5 is supported by spring 10, so that the side wall of the support plate 5 is supported on the inside of the stirrups. S3. Multiple stirrups pass through the limiting block 13 on the support plate 5 in sequence. During the movement of the stirrups, the limiting block 13 is rotated. When the stirrups have completely passed the limiting block 13, the limiting block 13 is restored to a position perpendicular to the support plate 5 by the torsion spring. Multiple stirrups are respectively attached to the side of a limiting block 13. The limiting block 13 limits the multiple stirrups so that the spacing between each stirrup is equal. S4. Insert multiple long-axis main ribs sequentially from the end of the support roller 4 into the middle of two adjacent support plates 5 along its length direction. The multiple main ribs are evenly distributed on the outside of the support roller 4. The outer wall of the main ribs contacts the inner side of the stirrups. The support roller 4 is driven to rotate intermittently by the motor 2 and the reducer 3, and the main ribs and stirrups are welded together in sequence. S5. After welding is completed, the electromagnetic rod 8 is energized, and the electromagnetic rod 8 generates a suction force, which attracts the connecting plate 11 and the support plate 5 to move into the groove 6, so that the side of the support plate 5 no longer abuts the inside of the stirrup. Then the steel cage, which is welded from multiple stirrups and main bars, is removed from the support roller 4, completing one production cycle. After that, the electromagnetic rod 8 is de-energized, and the support plate 5 is reset by the spring 10, so that the next manufacturing process can continue.
